lyndonli 9a02dae3bb drm/amdgpu: Fix call trace warning and hang when removing amdgpu device
[ Upstream commit 93bb18d2a8 ]

On GPUs with RAS enabled, below call trace and hang are observed when
shutting down device.

v2: use DRM device unplugged flag instead of shutdown flag as the check to
prevent memory wipe in shutdown stage.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
